This is animportant feature as it provides a displacement space `whereby room isprovided at the inner sides of the tires to insert tools for removingthe g tires and also the tiresare permitted to function individuallyA incontacting with the street surface.

Referring now to Fi 2, the wheel therein shown comprises a fel y 13 uponwhich are 1Q mounted the. three tires `havin respectively the rubbertreads 14, 15 endg 1 6 mounted upon the metal bands 17, 18 and 19. Thetwo outsidev tires namely those having the treads 14 and 16 are, it willbe seen, of the usy same construction as the tires of Fi 1. Theintermedi-ate tire having the 'tread 15 however, has its tread ish withthe metai Aband 18 atY bothsides as shown at 20 and 21 and both thesides are plane surfaces substantially per endicular to the tire axis.The wheel Wi th is thus .economized to the reatest degree,a rm andefficient tire prouced, i It will be seen that the intermediate tire 25ima be formed from the standard as shown `in ig. 3 by cutting away themetal and the rubber on both sides, the same as it is cut away on oneside to form the tires of Fig. 1, and the outside tires of Fi v hile'theinvention has in what are considered its best applications it may have'other embodiments Without departing from its spirit and is not limitedto the structures shown in the drawings.

What I claim is: The combination with a wheel, of' a plurality of tiresthereon, each of said tires prising a metal band and a rubber tread 2.een illustrated 30 mounted thereon, the two outside tires' having beadson their bands outside,their rub- 40 ber treads and at their oppositesides having the sides ofthe treads plane surfaces sub stantially7erpendicular to the tire axis and substantia ly flush with the saidmetal bands of the tires, an intermediate the sides of its rubber treadfaces substantially perpendicular axis and substantially Hush with ofits metal band.
